(No model.)

To all whom 2t may concern Be it known that we, CHARLES ALBERT and JOHNG. DINKELBIHLER, both of Cincinnati, Hamilton county, Ohio, haveinvented cer tain new and useful Improvements in Rotary Brushes, ofwhich the following is a specification.

This invention relates to those devices which are more especiallyemployed by barbers for removing dandruff from the human head; and theobject ofthe first part of our improvements is to construct a brushcapable of being readily operated and controlled by the barbers hands,as hereinafter more fully described, and pointed out in the claims.

The second part of our invention comprises a novel combination ofratchet-wheel, levers, pawls, connecting-rods, and a stop-pin, for thepurpose of operating with a double motion the gearing of suchhand-driven hair brushes, as hereinafter more fully described, andpointed out in the claims.

In the annexed drawings, Figure 1 is a side elevation of our machine.Fig. 2 is a rear elevation of the same, the metallicjacket of thebrush-block being sectioned. Fig. 3 is an elevation of the ratchet-feeddetached from the machine. Fig. 4 represents the preferred method ofsuspending our rotary brush.

A represents a light metallic frame, having at top a bar, a, for theconvenient suspension of said frame, within which isjournaled adriving-shaft, B, carrying the master-wheel O and ratchet-wheel D, thelatter being operated by the pawl e of lever E, that vibrates on saidshaft B. This lever has a heel, E, for a purpose that will presentlyappear, and is coupled to the operating-handle F by a link, G, saidhandle being pivoted at f to the frame A. Furthermore, the handle iseither bent at its lower end or has a loop, F, to receive theoperatorsright fingers, while its curved upper end has attached to it at f aconnecting-rod, H, loaded at h, or else depressed with a spring orequivalent device. This rod is coupled to a. lever, I, vibrating ondriving-shaft B, and carrying at one end a pawl, z, and at the otherendastop-pimi, projectingtoward the ratchetwheel D. Master-wheel 0 gearswith a pinion, J, of shaft j, to which latter is secured a wheel, K,that drives the pinion L of fiy-wheel shaft M. This shaft carries thefly-wheel N and a grooved pulley, 0, around which latter is passed theband P, that drives the grooved pulley Q of cylindrical brush-block R,this block beingjournaled in thelower part of frame A, as seen in Fig.2. Block R is surrounded with a metallic casing, jacket, or shell, S,through which project the bristles s, which should either be composed offine wire or should have a number of such wires introduced among saidbristles when the electrical attach ment is used.

'r r represent fingers for conducting the electrical current into thejacket S from the metallic frame A, which current may be generated withany suit-able magneto-machine, but preferably by two armatures, T T,secured to a cross-bar, m, of shaft M, said armatures being adapted torevolve in close proximity to a magnet, U. This magnet is attached tothe frame A by an insulated bearing, V.

W is a screen of wire or perforated sheet metal for the purpose ofpreventing dandruff, 850., being thrown into the barbers face by thecentrifugal action of brush 8.

1 X is a handle to be grasped by the barbers left hand, and Y is a loopto admit his right thumb.

Z is an elastic thong, band, or tube, having its upper end attached tothe ceiling of the barber-shop or other support, while its lower end isapplied to the bar a of the brush-frame. (See Fig. at.) A spring,however, may be substituted for this elastic support, the upper end ofthe latter being adapted to travel on a fixed bar or rail, so as torender one brush available for a number of chairs in the shop.

Our machine is so suspended from the elastic support Z as to be elevateda slight distance above the head of the person occupying the barberschair, thereby enablin g the operator to control the implement with thegreatest facility, which is done by grasping the handle X with the lefthand, and then inserting the thumb of the right hand in the loop Y, thusleaving the fingers of this hand at liberty to work the lever F. As thishandle F is drawn toward the frame A it is evident the pawl e actuatesthe ratchet-wheel D, and thereby starts the train of gear-wheels, whilethe opposite swing of said handle causes the other pawl, t, to operateon said wheel D. The

ratchet being thus operated with a double-1e ver movement hasconsiderable power imparted to it, and as a result of the peculiararrangement of the train of gears a very high velocity is transmitted tothe brush 8, which 5 rotates in the direction of the arrow seen in Fig.1, any dandruff thrown up by said brush being arrested by the screen W,which may have a small trough or receptacle at its lower edge to retainwhatever particles may be projected against said screen. As soon aslever E is brought to the position seen in Fig. 3 it comes in contactwith the stop-pin i, and is at once arrested,whilethccxtrcmeoppositestroke of said lever is limited by its heel E striking against said pin.

We claim as our invention- 1. The combination, in a hand-driven rotarybrush, of frame A, fixed handle X, and loops Y E, said loop F beingattached to the lever F, that actuates the gearing journaled in saidframe, substantially as herein described.

2. The combination, in a hand-driven rotary brush, of ratchet-wheel D,levers E E I, pawls e i, actuating-rods G H, and pin 2', which pinprojects from the heel of lever I, and serves as a stop for the heel Eof the other lever, E, as herein described.

In testimony whereof we affix our signatures in presence of twowitnesses.
